Error

Last week I started to work with CFX 5.6 and appeared many doubts when I try to simulate the same ( or very similar ) simulated before and processed with success in the CFX 5.5. The CFX 5.6 write the following erros (depend of the simulation): Error detected by routine PEEKCS; or writemms exited with non-zero return code 11 ; or | The CFX-5 solver could not be started: No child processes. No | | results file has been created.
